This present disclosure is directed to novel prodrugs of activated vitamin D3 compounds. The prodrugs can be designed to have one or more beneficial properties, such as selective inhibition of the enzyme CYP24, low calcemic activity, and anti-proliferative activity. Specifically, these prodrugs are 1-deoxy prohormones of active Vitamin D analogs, e.g. analogs of calcitriol. This disclosure is also directed to pharmaceutical and diagnostic compositions containing the prodrugs of the invention, and to their medical use, particularly as prodrugs in the treatment and/or prevention of diseases.

A mixed metal compound for pharmaceutical use is free from aluminium and has a phosphate binding capacity of at least 30%, by weight of the total weight of phosphate present, over a pH range of from 2-8. The compound is especially useful for treatment of hyperphosphataemia. The metals are preferably iron (III) and at least one of calcium, magnesium, lanthanum and cerium. A metal sulphate for pharmaceutical use is selected from at least one of calcium, lanthanum and cerium sulphate compounds and has a phosphate binding capacity of at least 30% by weight of the total phosphate present, over a pH range from 2-8.

The present invention provides a composition comprising (i) a mixed metal compound containing at least one trivalent metal selected from iron (lll) and aluminium and at least one divalent metal selected from of magnesium, iron, zinc, calcium, lanthanum and cerium, (ii) xanthan gum (iii) at least one of (a) polyvinyl pyrrolidone (b) locust bean gum (c) methyl cellulose wherein the composition has been irradiated with ionising radiation in an amount of at least 4 kGy.
